5. City list gets focus Event:

Mainly set in div: focusable="true" and @focus="onFocus"

<div>
          <div>
            <img  class="icon-location lazy" src="/static/imghwm/default1.png" data-src="@/assets/location.png" alt="An article explaining in detail Vue+flex layout to implement TV end city list" >
            <img  class="icon-location lazy" src="/static/imghwm/default1.png" data-src="@/assets/location_hot_focus.png" alt="An article explaining in detail Vue+flex layout to implement TV end city list" >
 </div>
<p><strong>6. Set focus background color and font effect:</strong></p>
<p> Mainly set: duplicateParentState="true" When the text gets focus, the color will not be affected by the parent layout. You can also set focus magnification and border effects </p>
<pre class="brush:php;toolbar:false">:enableFocusBorder="true"//设置获得焦点时的边框
:focusScale="1.0"//设置焦点放大时的倍数

Focus effect style: :style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}

<span>{{item.cityName}}</span>

7. Search box input event:

//输入内容之后请求城市列表接口刷新数据
endEditing(e) {
  console.log("--resultData--", this.citySearchResult)
},

8. The event when the search box gets focus:

onFocus(e) {
  this.focused = e.isFocused;
  this.$emit("onButtonFocused", e.isFocused);
},

9. The TV soft keyboard pops up by default:

mounted() {
  this.hotCity = hotCity;
  this.showHot = true;
  this.pageLoading = true
  //弹出软键盘
  this.$refs.searchInput.focus()
  //搜索框默认获取焦点
  this.setHideLoading()
},

10. The complete code is as follows:

<script>import searchImage from "@/assets/search_focus.png";import searchBackGroundImage from "@/assets/index-bg-qing.jpg";import {hotCity} from &#39;@/views/contsants&#39;;import {ESLaunchManager} from "@extscreen/es-core";export default {
  name: "city_list",
  props: {
    searchKeyWord: {
      type: String,
      default: &#39;&#39;,
    },
    focusTextColor: {
      type: String,
      default: &#39;#000000&#39;
    },
    focusHotTextColor: {
      type: String,
      default: &#39;#00EFFF&#39;
    },
    textColor: {
      type: String,
      default: &#39;#FFFFFF&#39;
    },
    textFontSize: {
      type: String,
      default: &#39;30px&#39;
    },
    textFontWeight: {
      type: Number,
      default: 400
    },
    focusBackground: {
      orientation: &#39;TL_BR&#39;,//TOP_BOTTOM,TR_BL, RIGHT_LEFT, BR_TL, BOTTOM_TOP,BL_TR,LEFT_RIGHT,TL_BR,
      cornerRadius: [40, 40, 40, 40],
      normal: [&#39;#00000000&#39;, &#39;#00000000&#39;],
      focused: [&#39;#F5F5F5&#39;, &#39;#F5F5F5&#39;],
    },
  },
  data() {
    return {
      pageLoading: false,
      text: &#39;search city&#39;,
      search: &#39;&#39;,
      searchIcon: searchImage,
      searchImageData: searchBackGroundImage,
      searchTitle: "切换城市",
      searchDefaultKeyWord: &#39;搜索&#39;,
      searchDefault: &#39;请输入城市名称首字母或全拼&#39;,
      focusColor: &#39;#f5f5f5&#39;,
      citySearchResult: "",
      hotCity: [],
      cityName: "",
      cityId: "",
      showHot: true,
      params: &#39;&#39;,
    }
  },
  activated() {
  },
  deactivated() {
    this.resetModel()
  },
  mounted() {
    this.hotCity = hotCity;
    this.showHot = true;
    this.pageLoading = true
    //弹出软键盘
    this.$refs.searchInput.focus()
    //搜索框默认获取焦点
    this.setHideLoading()
  },
  methods: {
    setHideLoading() {
      setTimeout(() => {
        this.pageLoading = false
      }, 500)
    },
    onFocus(e) {
      this.focused = e.isFocused;
      this.$emit("onButtonFocused", e.isFocused);
    },
    //输入内容之后请求城市
    endEditing(e) {
      console.log("--resultData--", this.citySearchResult)
    },
    onBackPressed() {
      ESLaunchManager.finishESPage();
    },
    resetModel() {
      this.citySearchResult = "";
      this.hotCity = [];
      this.pageLoading = false;
      this.searchTitle = "";
      this.searchDefaultKeyWord = "";
      this.searchDefault = "";
    },
  }
}</script>

react与vue的虚拟dom没有区别;react和vue的虚拟dom都是用js对象来模拟真实DOM,用虚拟DOM的diff来最小化更新真实DOM,可以减小不必要的性能损耗,按颗粒度分为不同的类型比较同层级dom节点,进行增、删、移的操作。
